GPT Review — 09 rev6 Minimal Implementation Planning Pack

Date: 2026-05-04 Method: GPT checked actual KB document knowledge/dev/laws/dieu44-trien-khai/design/09-iu0-minimal-implementation-planning-pack.md revision 6, not only Opus report.

Verdict

PASS for planning quality. 09 rev6 fixes the five issues raised in GPT review rev1: deleted_at present, creation transaction timing clarified, U9/container semantics clarified, publication pilot WARN vs production BLOCK clarified, implementation sequencing grouped into 3 packs, and P44-6 pre-open checklist added.

Plain image: the cabinet blueprint is now structurally clear enough to ask whether we should open the workshop. But before cutting wood, we still need an APR/DDL package and rollback plan.

Actual checks

• Header/range remains PLANNING only. GR-2 and GR-3 remain active. No DDL/code/migration is introduced.
• §2.1 now includes deleted_at as soft-delete lifecycle field.
• §2.4 now defines the creation transaction: insert unit with temporary version_anchor_ref = NULL, insert version, update anchor, run deferred birth gate, commit or rollback.
• §4 clarifies U9: nullable for root units, child slices use parent unit_id.
• §4 clarifies publication fields: pilot WARN, production BLOCK.
• §7.1 adds C1-C10 pre-open checklist.
• §9 compresses I-1..I-8 into 3 implementation packs with gates.
• Conflict check remains aligned with IU-0 baseline, P38-XC UMC, P44-3 profile, GR/VG guardrails.

Remaining non-blocking concerns for P44-6 opening

• Pack 1 still needs a real APR/DDL design and rollback plan before execution.
• The phrase “Birth gate trigger kiểm trước INSERT” in §4 is slightly stale compared with §2.4 deferred timing. It is not fatal because §2.4 is explicit, but Opus should patch wording to “kiểm trong transaction / before COMMIT” to avoid implementation confusion.
• Q4 in §10 asks when User is ready to open P44-6; GPT should not push this until a pre-open decision note summarizes C1-C10 status and asks User explicitly.

Directive

Opus should perform one tiny patch to §4 wording only:

• Replace “Trigger kiểm trước INSERT” with “Birth gate kiểm trong creation transaction, sau khi unit + version + anchor đã đủ, trước COMMIT”.

Then create a short P44-6 pre-open decision note (not a long doc) summarizing:

• C1-C7 PASS based on 09 rev6;
• C8 rollback plan = pending;
• C9 legacy vector impact zero = PASS;
• C10 User explicit approval = pending;
• recommendation: prepare Pack 1 APR/DDL design, not execute.

No Agent dispatch and no DDL/code yet.
